community.docker.docker_image – Manage docker images
Note
This plugin is part of the community.docker collection (version 1.10.0).
You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.
To install it, use: ansible-galaxy collection install community.docker.
To use it in a playbook, specify: community.docker.docker_image.
Synopsis
- Build, load or pull an image, making the image available for creating containers. Also supports tagging an image, pushing an image, and archiving an image to a 
.tarfile. 
Requirements
The below requirements are needed on the host that executes this module.
- Docker API >= 1.20
 - Docker SDK for Python: Please note that the docker-py Python module has been superseded by docker (see here for details). For Python 2.6, 
docker-pymust be used. Otherwise, it is recommended to install thedockerPython module. Note that both modules should not be installed at the same time. Also note that when both modules are installed and one of them is uninstalled, the other might no longer function and a reinstall of it is required. - Docker SDK for Python >= 1.8.0 (use docker-py for Python 2.6)

        Make assertions about the state of an image.
        
       
        When  
       absent an image will be removed. Use the force option to un-tag and remove all images matching the provided name.
       
        When  present check if an image exists using the provided name and tag. If the image is not found or the force option is used, the image will either be pulled, built or loaded, depending on the source option.

        string
         |

        Secure the connection to the API by using TLS without verifying the authenticity of the Docker host server. Note that if validate_certs is set to  
       yes as well, it will take precedence.
       
        If the value is not specified in the task, the value of environment variable  DOCKER_TLS will be used instead. If the environment variable is not set, the default value will be used.

       DOCKER_TLS_HOSTNAME will be used instead. If the environment variable is not set, the default value will be used.
       
        The current default value is  localhost. This default is deprecated and will change in community.docker 2.0.0 to be a value computed from docker_host. Explicitly specify localhost to make sure this value will still be used, and to disable the deprecation message which will be shown otherwise.

Notes
Note
- Connect to the Docker daemon by providing parameters with each task or by defining environment variables. You can define 
DOCKER_HOST,DOCKER_TLS_HOSTNAME,DOCKER_API_VERSION,DOCKER_CERT_PATH,DOCKER_SSL_VERSION,DOCKER_TLS,DOCKER_TLS_VERIFYandDOCKER_TIMEOUT. If you are using docker machine, run the script shipped with the product that sets up the environment. It will set these variables for you. See https://docs.docker.com/machine/reference/env/ for more details. - When connecting to Docker daemon with TLS, you might need to install additional Python packages. For the Docker SDK for Python, version 2.4 or newer, this can be done by installing 
docker[tls]with ansible.builtin.pip. - Note that the Docker SDK for Python only allows to specify the path to the Docker configuration for very few functions. In general, it will use 
$HOME/.docker/config.jsonif theDOCKER_CONFIGenvironment variable is not specified, and use$DOCKER_CONFIG/config.jsonotherwise. - This module uses the Docker SDK for Python to communicate with the Docker daemon.
